MREs residing in Switzerland face a fiscal system unique in Europe: three-tier taxation (federal, cantonal, communal) with rates varying widely between cantons. The Switzerland-Morocco tax treaty of 31 March 1993 (in force since 27 July 1995) allocates taxing rights between the two States under the OECD model. Absolute distinctive feature: Switzerland has NOT signed a social security agreement with Morocco. Consequence for MREs: Swiss AVS contributions and Moroccan CNSS contributions do not totalise. This guide details the 2026 fiscal mechanics, reporting obligations with the Federal Tax Administration (AFC) and cantonal administrations, and the social security blind spots.

Timeline
Swiss tax residence: 90 days without activity or 30 days with activity
The Swiss federal direct tax law (LIFD article 3) defines Swiss tax residence by two alternative criteria: (1) 30 consecutive days with gainful activity, or (2) 90 consecutive days without gainful activity. Beyond these thresholds, you become a Swiss tax resident and taxable on worldwide income (unlimited liability). Non-residents are subject to limited liability: taxation only on Swiss-source income (real estate, dividends, salaries from activity exercised in Switzerland). The 1993 treaty (article 4) provides classic tie-breaker rules (permanent home, centre of vital interests, habitual abode, nationality) for dual residence conflicts with Morocco. Important: Switzerland authorises certain lump-sum taxation (expenditure-based taxation) for wealthy foreign nationals without gainful activity in Switzerland, under strict conditions in LIFD article 14.
💡 Tip: The Swiss tax residence certificate is requested from the cantonal tax authority of the canton of domicile (form varies by canton). It is requested to invoke the treaty in Morocco.
⚠️ Warning: Each Swiss canton has its own rules, rates and filing deadlines. Geneva, Vaud, Zurich, Bern, Ticino, Basel-City: declarations are NOT interchangeable. Verify your canton's calendar.
Earned income: article 15 treaty and source taxation
Article 15 assigns salaries to the country of activity, except missions under 183 days with non-resident employer without permanent establishment. For a Swiss resident MRE with Swiss salaried activity: source taxation (Quellensteuer) if foreigner without C permit, then ordinary declaration above a certain income threshold set by Swiss law. C permit holders (settlement permit) are subject to ordinary declaration. If you also receive Moroccan salary (dual employment, Moroccan board membership), this income is taxable in Morocco (Moroccan IR), then declared in Switzerland with exemption subject to progression (Switzerland applies the exemption method, article 23 treaty 1993). Moroccan income is not taxed in Switzerland but enters into the rate calculation applicable to Swiss income.
⚠️ Warning: Swiss source taxation (Quellensteuer) is flat. Above a certain income threshold, or if you own real estate in Switzerland, the ordinary declaration procedure applies; thresholds are set by Swiss law.
Pensions, AVS and the critical absence of social security agreement
Article 18 of the 1993 treaty assigns private pensions to the State of residence of the beneficiary. A retiree MRE residing in Switzerland receiving a Moroccan CNSS pension is taxed in Switzerland (federal, cantonal and communal tax). Moroccan public pension (RCAR, CMR civil servants) remains taxable in Morocco under article 19. But the major Switzerland-Morocco peculiarity concerns social security: there is NO bilateral social security agreement between the two countries (unlike France, Belgium, Netherlands, Germany, Spain, Portugal which have one). Concrete consequences: (1) Swiss AVS/AI/APG contributions and Moroccan CNSS do not totalise to meet minimum durations (1,320 days CNSS, 1 year AVS minimum); (2) an MRE who contributed 5 years in Switzerland then returns to Morocco cannot combine these 5 years to validate a Moroccan pension; (3) conversely, a worker who contributed 8 years in Morocco then comes to Switzerland will have to contribute independently to AVS without counting Moroccan quarters. Partial solution: AVS contribution buyback (under conditions) and voluntary CNSS contribution from abroad to maintain Moroccan history.
💡 Tip: For an MRE currently contributing in Switzerland but considering return to Morocco, a voluntary CNSS contribution from abroad exists to maintain Moroccan history (conditions with the CNSS). See our voluntary CNSS contribution MRE guide.
⚠️ Warning: The absence of Switzerland-Morocco social security agreement has a major hidden cost: an MRE who splits their career between the two countries may end up with NO pension at retirement if they validate neither the Swiss minimum duration (1 year AVS for partial pension) nor the Moroccan minimum duration (1,320 days CNSS).
Swiss dividends: anticipatory tax and treaty refund
Switzerland applies a withholding tax on dividends (Swiss anticipatory tax). For a Moroccan resident benefiting from the 1993 treaty, the anticipatory tax can be partly refunded under the AFC procedure (refund request for applicants resident abroad, form 60), accompanied by a residence certificate. Rates and deadlines are stated on the AFC website. Article 11 caps interest withholding at 10%. Article 12 caps royalties at 10%. For dividends paid by a Moroccan company to a Swiss resident: Moroccan tax capped at 15% (7% for a holding of at least 25% of the capital), according to the overview published by the AFC.
💡 Tip: The refund request form for applicants resident abroad (form 60) is published on the AFC website.
⚠️ Warning: The refund of the Swiss anticipatory tax follows an AFC procedure whose deadlines are stated on its website.
Rental income and capital gains: articles 6 and 13 treaty 1993
Article 6 assigns rental income to the State of property location: your Moroccan rents are taxable in Morocco (Moroccan income tax after a 40% allowance, with withholding of 10% or 15% depending on gross rents when the tenant is a legal entity; the 5% withholding of the 2026 finance law concerns rental income paid to individuals under the actual or simplified net result regime, not the property income of private individuals). This income remains to be declared in Switzerland for the progression reserve (exemption method, article 23). Article 13 assigns real estate capital gains to the State of property location: selling a flat in Casablanca = Moroccan income tax on property profits (20%) (exemption if main residence for at least 5 years, CGI art. 63-II-B). The capital gain is exempt in Switzerland but enters into the progressive rate calculation. For a Swiss resident MRE owning property in Switzerland: taxable rental value (Eigenmietwert) on main residence, mortgage and maintenance deductions, and real estate capital gain subject to cantonal tax on real estate gains (rate varies by canton and holding period).
⚠️ Warning: The Swiss rental value (Eigenmietwert) is fictitious imputed income taxable on the main residence you own in Switzerland. Its abolition was the subject of a federal vote on 28 September 2025; the applicable rules can be consulted with the cantonal tax authority.
In depth
The mechanism for eliminating double taxation in Switzerland is based on the exemption method with progression reserve (article 23 of the 1993 treaty). Concretely: Moroccan income covered by the treaty is exempt from Swiss tax, but it is still taken into account to determine the tax rate applicable to Swiss income. Numerical example: a Swiss resident MRE in Geneva earns 80,000 CHF in Switzerland and 20,000 CHF of Moroccan rents. The 20,000 CHF Moroccan is not taxed in Switzerland, but the Swiss tax rate is calculated as if total income was 100,000 CHF. This progression reserve mechanism can significantly increase Swiss tax on Swiss income, particularly for modest incomes. For Swiss dividends paid to a Moroccan resident, the Swiss anticipatory tax is withheld at source and can then be partly refunded under the AFC procedure. Social security is the main point of vigilance for MREs residing in Switzerland: there is no social security agreement between Switzerland and Morocco.
❌ Common mistakes to avoid
- ✕Ignoring the absence of Switzerland-Morocco social security agreement: direct impact on retirement.
- ✕Not claiming the refund of the Swiss anticipatory tax to which the convention may give entitlement (AFC procedure, form 60).
- ✕Confusing cantonal calendars: each canton has its own deadline.
- ✕Forgetting to declare Moroccan income exempt in Switzerland: it must be declared for progression reserve, under penalty of fine.
- ✕Believing one is taxable in Switzerland from 30 days regardless of reason: this threshold only applies with gainful activity. Without activity, threshold is 90 days.
- ✕Wanting to benefit from cantonal lump-sum taxation while exercising gainful activity in Switzerland: this status is reserved for persons without gainful activity in Switzerland (LIFD article 14).
